Assertion: Protoplast fusion is one of the major advantages of tissue culture
Reason: The naked protoplasts of two different plants fuse to form a hybrid.

Options

A. If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion.
B. If both Assertion and Reason are true and the Reason is not the Reason is not the correct explanation of the assertion
C. If assertion is true but the Reason are false
D. If both Assertion and Reason are false

Answer

To analyze the assertion and reason provided in the question, we can break down the solution into the following steps:

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that "Protoplast fusion is one of the major advantages of tissue culture." This means that protoplast fusion is beneficial in the context of tissue culture techniques.

2. **Understanding the Reason**: The reason given is that "The naked protoplasts of two different plants fuse to form a hybrid." This explains how protoplast fusion occurs, highlighting that it involves the fusion of protoplasts (the living part of a plant cell without its cell wall) from two different plant species.

3. **Explaining Protoplast Fusion**: Protoplast fusion is a technique where the cell walls of two different plant cells are removed, allowing their protoplasts to merge. This fusion can lead to the creation of a hybrid cell that contains genetic material from both parent plants.

4. **Linking the Assertion and Reason**: The assertion is supported by the reason because the ability to fuse protoplasts from different plants to create hybrids is indeed a significant advantage of tissue culture. This technique allows for the combination of desirable traits from different species, which can lead to improved plant varieties.

5. **Conclusion**: Both the assertion and the reason are true. The reason provided explains why protoplast fusion is considered an advantage in tissue culture, making it a valid justification for the assertion.

### Final Answer:
Both the assertion and reason are correct, and the reason is a correct explanation of the assertion.
